Illuminae by Amie Kaufman and Jay Kristoff
The year is 2575, and two rival megacorporations are at war over a planet that’s little more than an ice-covered speck at the edge of the universe. Too bad nobody thought to warn the people living on it. With enemy fire raining down on them, Kady and Ezra—who are barely even talking to each other—are forced to fight their way onto an evacuating fleet, with an enemy warship in hot pursuit.
But their problems are just getting started. A deadly plague has broken out and is mutating, with terrifying results; the fleet's AI, which should be protecting them, may actually be their enemy; and nobody in charge will say what’s really going on. As Kady hacks into a tangled web of data to find the truth, it's clear only one person can help her bring it all to light: the ex-boyfriend she swore she'd never speak to again.
BRIEFING NOTE: Told through a fascinating dossier of hacked documents—including emails, schematics, military files, IMs, medical reports, interviews, and more—Illuminae is the first book in a heart-stopping, high-octane trilogy about lives interrupted, the price of truth, and the courage of everyday heroes.
Kady chose the perfect day to break up with her boyfriend: the day their homes get destroyed. Separated on different rescue ships, Kady and Ezra seem closer together than they ever were when they were actually together. With her coding genius, Kady begins to unmask the real reason their homes were destroyed. The ships’ commands are keeping a lot of things from its civilians. In order to get to the bottom of this mess, she involves Ezra because this is no longer something as small as them. A war is starting and Kady is the only one with the tools to stop it.
